It's nothing special but in decent condition. it's probably for about ages 8-11 or something. I was thinking selling it for $30 but don't know if that's too low.
Also, where would be a good place to sell it to?
you could try selling it on somewhere like ebay or amazon. About the price if you put it on for £30 on some where like ebay if it is really nice it will probably go up.
